[gst-devel] Problem using gnomevfs plugin and ssh

[Tiago Katcipis]

i updated my gnomevfs to version 2.24.2 (it was 2.24.0) and gstreamer /
gstreamer base to 0.10.25.2 (it was 0.10.25) and it get no more glib
error*failed to allocate
*, and the application no longer crashes, but all the warnings on
gnome-vfs-modules are still there. Don't know if the bug is really
corrected.
